AutoGRAPH-ST
•
USER MANUAL
Coordinate acquisition
When the device is in Operation mode, it determines its position using
global navigation system GLONASS and GPS (NAVSTAR). If it is unable to
determine its position using GNSS, the device will determine its approximate
GSM localization using the Yandex.Locator Service. Position accuracy, when
fixing in relation to a GSM base station, can attain 1 km in city and 30 km in
the country.
If GPRS or Yandex.Locator Service are not available, the device will send
the characteristics of the base station which it is connected to and the
characteristics of the six nearest stations.
Recording the data
The device can be specified to acquire and record current coordinates
into internal memory without sending it to the customer. The period of data
recording
is configurable and can be set using SMS command or the
AGSTConf program.
If the device's current profile enables data transfer to a data server, all collected
data will be transferred to the server in the next period of data transmission.
Also the collected data can be read via USB into the AutoGRAPH Dispatch
Software.
Along with the device coordinates, ambient temperature, battery voltage and
speed are also saved in the internal memory.
Data transmission
The AutoGRAPH-ST is capable of transferring data to a data server by GPRS,
to telephone numbers by SMS and to email addresses by Email.
If data transfer to a server is enabled, the device will transfer current position
and collected data from the internal memory to the specified server. If
the device is unable to transfer data to the server, e.g. because of GPRS
unavailability, the device will retry during the next transmission period.
